A Look Inside: Master Lock Key Safe

A look at the mechanism inside a Master Lock keysafe.
Also, a look back at my original video on this lock

Great video of the tear down and operation. Glad you pointed out the difference between the original version and new version.

[@terataiministudio4263]

Thanks a lot for this video. I successfully repair my keysafe after watching your video. Save my money from buying a new one😅.

Thankyou! This helped me break back into my keysafe that I forgot the code too 😀

[@stonermountin4881]

For context/disclaimer: I fully owned that keysafe. I didn't break into anyone else's but my own

[@wintersun398]

I forgot the combination to one of these safes. I actually made a shim from the plastic packaging from the product! 3 of the wheels were very easy to decode, but the other I couldnt feel the flat as it was a slightly closer tolerance. So i just rotated the 3 I knew back to the correct spot, then just rotated the remaining wheel until it unlocked. Easy!

Thanks for the teardown and explanation! Great job

[@FrakkingCreations]

Nice video... Never seen them torn apart before.

[@hectorpatricio9918]

VERY GOOD EXPLAIN. DO TO ASSEMBLE. TY

4:05 I used a drill to enlarge the pin holes by sides, then I used metal screws to mount the lock back.

Thank you for this - helped me repair my 'Reinforced' version after one of my kids locked it (whilst open). I tore it down aligned the cams and rebuilt. The inside was similar but a bit different - I'm no locksmith but a couple of the changes seem to 'fix' the issues you mentioned e.g. the design of the 'wheels' is different. Have you looked into this version?

[@childscraig]

I haven't seen the new version

[@brandonnguyen7266]

Very nice and very effective

[@c0lin147]

great video. I tried for hours but looks like the lip on the gear is impossible to get past due to upgrade maybe?

[@Dannydawson537]

Great vid nicely done ✅ my block of flats is due for demolition and the council are using these when people move out so the council can access the flats 😂😂 all the copper boilers will be nicked

[@antzzworld6409]

well played lol

[@Rockercaruthonyoutube]

Well the council are stupid enough to put these on buildings most council employees have an iq of 5 and a stupidity.level of 205% you,ll move out. Squatters move in. No probs.

[@casacarol2034]

❤️🙏😅 Thank you. God bless. It worked!!!

[@triumphspitfirerestoration4772]

What is the little black clip on the bottom of the box? What does it do ?

[@childscraig]

It's for clipping keys onto it stops them falling out when you open the door. I have never seen it being used and I access keysafes frequently!

[@triumphspitfirerestoration4772]

@@childscraig are you sure as I have taken it out and shut it now I can’t open!

[@childscraig]

@@triumphspitfirerestoration4772 it's maybe a spring to open the door then, tbh I never paid much attention to that part!

[@Jack-fs2im]

[@roybertelli403]

I MUST BE THE FAILURE OF THE CLASS,,WE USE THE 5400 D ALL THE TIME AND OF COURSE WE GET SOME (THREE NOW) THAT COME BACK BUGGERED UP....I CAN NOT OPEN THEM) TRIED FOR HOURS...

[@childscraig]

The newer models hsve been redesigned to remove this flaw, you can still use shims to feel the tumbler though, just takes a lot more patience. C.

[@danielmusson4522]

How do you put the copper thing back on the mechanism?

[@childscraig]

Hi Daniel, I didn't put mine back, the process was one way for me, I didn't intend to rebuild the lock. C.

[@danielmusson4522]

@@childscraig Thank you for reply,Craig

[@detoast1197]

get on with it ffs

[@jaredbruns9738]

Wow, think you gave us enough of a back story? Do us a favor, next time title your video as "A long explanation about nothing".

[@jaredbruns9738]

Absolutely waste of time video

[@eternalele9309]

Take no notice. It was a well explained video.
